Abstract (en)
A gas turbine engine component is provided. The gas turbine engine component has an internal cooling passage (32) having first endwall (37) and a second endwall (39). A primary inlet aperture (36a) is in fluid communication with a coolant supply and the first end of the internal cooling passage (32). An elongated rib (40) is inside the internal cooling passage (32) and proximate the primary inlet aperture (36a). The elongated rib (40) is configured to direct at least a portion of the coolant from the primary inlet aperture (36a) against a proximate one of the first or second endwall (37, 39) and then substantially reverse direction to flow downstream toward a second end of the internal cooling passage (32). A blade outer air seal ("BOAS") assembly and a BOAS segment (30) thereof are also provided.
